Turn your filter system off and open the backwash valve. Using the bump handle, bump the filter slowly 15 times. With the backwash valve still open turn your filter system back on and let it run for about two minutes. This will rinse out all of the DE that you shook off the fingers in your DE Filter.
Turn the filter system off and repeat this again to ensure all of the DE has been rinsed out. Bump it slowly 15 times and turn your system back on for about a minute or so.
Shut your filter system off now and replace the cap or close off your backwash valve and now start your filter system back up. Add more fresh DE to your skimmer.
We recommend you follow the manufactures instructions on how much DE to add. Below is a guide for Hayward owners For Hayward EC-40 / EC-50 Filters add (3) Lbs. of DE For Hayward EC-65 / EC-75 Filters add (5) Lbs. of DE
